I wholeheartedly agree with Jammingammon as to saving versions incrementally, especially when you’re putting your heart and soul into a project. I just finished the Pothead Course and I must have saved over 50 versions so I wouldn’t lose any work. I’m using an experimental version of Blender and often have a movie or music playing too so spontaneous crashes were common. I never lost a significant amount of work though because of how many versions I had saved.
